Percutaneous Release of the Finger Joints and Mini-Open Intrinsic Release With Tenolysis: A Cadaveric Study

Published:February 15, 2019DOI:


      To evaluate the effectiveness and safety of minimally invasive distal intrinsic release and extensor tenolysis combined with percutaneous release of proximal and distal interphalangeal joint collateral ligaments.


      The procedures were performed on 5 cadaveric upper extremity specimens, followed by a full anatomical dissection to assess completeness of the targeted releases and any damage to surrounding structures.


      Complete distal intrinsic release, dorsal capsule release, and distal interphalangeal collateral ligament release was performed on all specimens. We achieved complete release of all proximal interphalangeal joint collateral ligaments in 38 of 40 specimens (95%). We noted damage to nontargeted structures in 2 instances (5%).


      Minimally invasive and percutaneous techniques can effectively release several structures known to cause finger stiffness with minimal damage to surrounding structures.

      Clinical relevance

      If similar results are seen in clinical trials, this could be a quick and easy way to increase the mobility of a stiff finger with potentially minimal morbidity.
